Subject: [PATCH next] driver core: auxiliary bus: Fix IS_ERR() vs NULL check
 in __devm_auxiliary_device_create()

The auxiliary_device_create() function returns NULL.  It doesn't return
error pointers.  Update the checking to match.

Fixes: eaa0d30216c1 ("driver core: auxiliary bus: add device creation helpers")
